SPECIFICATIONS
General
Furnish one (1) Gaylord ClearAir Pollution Control Unit model
RSPC-ESP series as manufactured by Gaylord Industries
Inc. of Tualatin, Oregon in accordance with the following:
The pollution control unit shall consist of a smoke control sec-
tion, odor control section (optional) and an exhaust fan section
(optional) all built on a common base as an integral unit.
Smoke Control Section
The smoke control section shall contain one or more
electrostatic precipitator (ESP) cells to remove smoke
particles from the air stream to a level no higher than 20%
opacity when operated in accordance with the operation
and maintenance guidelines. The ESP cells shall be of a
floating plate design to eliminate plate warpage during high
heat operation. The cells shall be positioned on slide tracks
so that they may be easily removed through a hinged cell
access door(s). For ease of handling, individual cells shall
weigh less than 54 lbs. There shall be removable, cleanable
debris screens located immediately upstream of the ESP
cells and a moisture separator immediately downstream. An
electrical panel mounted on the unit shall contain the high
voltage power pack assembly, safety disconnect switch,
main disconnect switch, fuses and a magnetic starter for
the exhaust fan when fan is included. The safety discon-
nect switch shall interface with the electrical panel access
door such that when opened it will shut off service to the
power pack(s) and ground them to drain the residual elec-
trical charge from both the power pack(s) and ESP cells.
The ESP cell access door shall interface with the electrical
panel access door so that it cannot be opened without first
opening the electrical panel access door. The high volt-
age power pack(s) shall be self-limiting type and shall be
self contained. The electrical panel shall include indicating
lights to monitor cell and transformer voltage. The main
disconnect switch for the exhaust fan and control circuits
shall lock the electrical panel access door closed when in
the “on” position. The unit shall contain one or more wash
manifold(s) with brass spray nozzles to wash the ESP cells
with hot detergent injected water each time the exhaust
fan is shut off.
Fire Detection
A thermostat, set at 250
o
F, shall also be located in the filter
section to shut down the exhaust fan in the event of a fire.
Optional Fire Damper for use in Canada
The unit shall include a UL listed fire damper, with a 280
o
F fusible link, located downstream of the filters to prevent
passage of fire to the duct downstream of the unit
Odor Control Options
Media bed of 50/50 Blend Potassium Permanganate and
Carbon Blend
The unit shall be provided with odor control utilizing a media
bed of 50% potassium permanganate 50% carbon blend.
There are two design methods of housing the media used
in the ClearAir unit. One is called the Loose Fill type and
the other is called the Media Panel type.
Loose Fill type – The odor control media shall be housed
in steel reusable Media Modules that can be replenished
with Loose Fill media. There shall be a 30% pleated media
After Filter located immediately downstream of the Media
Models. The Modules and After Filters shall be mounted
into slide tracks to prevent air bypass around the ends. The
Modules and After Filters shall be removable through side
access doors with lift and turn latches.
Media Panel type – The odor control media shall be com-
pressed into Media Panels that slide into Media Modules.
The Modules shall be mounted into slide tracks to prevent
air bypass around the ends. The Modules and shall be re-
movable through side access doors with lift and turn latches.
(
optional) The unit shall be equipped with a 30% pleated
media After Filter located immediately downstream of the
Media Models.
The unit shall be equipped with a Single Pass Media Bed
The unit shall be equipped with a Double Pass Media Bed
The unit shall be equipped with a Triple Pass Media Bed
Spray Odor Control
The unit shall be provided with a spray odor control sys-
tem utilizing an odor neutralizer chemical. The odor spray
control cabinet shall be mounted on the side of the unit and
shall contain a liquid spray compressor piped to the spray
nozzle in the fan plenum, adjustable delay timers with fuse
protected circuitry factory wired to the unit electrical panel.
The cabinet shall include one 5 gallon container of Gaylord
Formula GS-710 Odor Neutralizer. The cabinet shall con-
tain a heater to prevent freezing of the odor neutralizer, if
mounted outdoors.
Exhaust Fan Options
Exhaust Fan (Standard Centrifugal Fan)
The unit shall include a centrifugal exhaust fan. The exhaust
fan shall be an SWSI upblast arrangement #9 or #10 with a
non-overloading BI or AF wheel. The motor, drives, bearings
and fan mounting base shall be located out of the exhaust
air stream as required by the IMC (International Mechanical
Code) and NFPA-96. The fan shall be AMCA certified and
bear the AMCA seal for performance. The fan housing shall
be constructed of heavy gauge steel. The fan bearings shall
be heavy duty self-aligning pillow block type rigidly mounted
on heavy structural steel supports. The motor shall be ODP
three phase mounted on a common base with the fan and
shall be pre-wired to the electrical cabinet located on the unit.
The electrical cabinet shall include a disconnect switch, motor
starter, overloads and fuses. The factory provided drive as-
sembly shall be adjustable pitch on 5 HP and smaller, fixed
pitch on 7.5 HP and larger. It shall also be sized for a minimum
1.5 service factor. After final system balancing, fixed pitch
sheaves shall be provided and installed by the air balancing
contractor to provide proper flow at actual installed conditions.
Exhaust Fan (Optional Tubular Fan)
The unit shall include a tubular centrifugal exhaust fan. The ex-
haust fan shall be an arrangement #10 with a non-overloading
BI, AF wheel. The motor, drives, bearings and fan mounting
